Adam Hadwin has opened up a four-stroke lead at the top of the Valspar Championship leaderboard after carding a third-round 67 in Florida.
The 29-year-old raced ahead on day two and was able to push on during Saturday's session, making a bogey-free round to move further ahead of the chasing pack.
Hadwin, who has never previously won on the PGA Tour, recorded four birdies to take him to 14-under-par for the tournament, four strokes ahead of Patrick Cantlay and five in front of Jim Herman.
Cantlay impressed with five birdies in a round of 66 to overtake early leader Herman, whose back-to-back rounds of 71 leaves him in third place heading into the final day.
Two more Americans make up the top five as Dominic Bozzelli (-8) is in fourth, while JJ Henry and Henrik Stenson are in a tie for fifth on seven-under.
